Upgrading to iOS 5 delivered a lot of powerful new capabilities to the iPhone and iPad, from Notification Center to iCloud. But these features can take a toll on battery life. There are plenty of other power-hogging settings and activities you need to be aware of in order to make your device last. Admittedly, applying all these battery tips can make your iDevice rather dull. Our advice? Choose the fixes presented below that you can live with.
Having your iPhone constantly on alert for incoming messages can drain its battery in a hurry, so be sure to turn push email off. You can schedule your iPhone to check for new messages at regular intervals: every 15 minutes, every 30 minutes, every hour or manually. We suggest selecting manually for those who want to save the most power. Data will still be delivered instantly to your device when you use an app that requests it, such as Mail.
To turn push email off:
This one’s a no-brainer. Leaving your Wi-Fi setting on means your phone is actively searching for a Wi-Fi connection even after you’ve left your home or office. This process taxes your battery and drains some of its power.
To turn off Wi-Fi:
Bonus Tip: If you prefer to keep Wi-Fi on but hate it when your iPhone automatically asks you to join Wi-Fi networks, you can turn that setting off right from this screen.

The easiest way to stop your iPhone from keeping tabs on your location at all times—and draining your battery in the process—is to shut down Location Services.

Here’s how to fine-tune Location Services:
If you’re really concerned about location eating up battery power, you can tweak System Services. We recommend toggling off the switches for Setting Time Zone (unless you’re traveling and need this to be activated), Location-Based iAds and Diagnostics & Usage.
How to tweak System Services:
Whether you’re downloading a big app, a movie or a TV show, it’s best to get that content over a Wi-Fi connection instead of 3G. You’ll likely have a faster connection via Wi-Fi, and the time it takes to download will be shorter, which saves power. Plus, 3G is more power hungry than Wi-Fi.
An iOS 5 device can notify you every time there’s a new alert, lighting up your iPhone’s screen to catch your attention. The problem is that your display uses power, and over time all these little reminders will add up to less endurance.
Here’s how to manage Notifications:
Bonus Tip: Move multiple applications to the “Not in Notification Center” group.
